过负荷记录仪器分为单片机数据采集器和微机数据分析记录数据库软件两部分。 仪器具有监视变压器负荷电流（通过改变传感器也可记录最低电压）并自动记录过负荷电流出现的开始时间，最大值和结束时间的功能。当前版本可保存150次的过负荷数据。并可根据需要扩充。pc机软件具有和仪器通信的能力，能够把仪器采集的数据集中保存，并能进行查询，统计等处理。使用本仪器可以定量分析变压器的过负荷情况。 本原码为PC机部分,使用了串口通信和数据库技术 -Overload apparatus records are divided into single-chip data acquisition and data analysis microcomputer database software records in two parts. Surveillance equipment with transformer load current (by changing the sensor can also record the minimum voltage) and automatically recorded the load current emerging start time, maximum and end times of the function. 150 to save the current version of data overload. And in accordance with the need to expand. pc software and equipment with communication capability to the instrument collected data centrally stored, and can query, statistics and other treatment. Use of the device which can be quantitative analysis of transformer overload situation. Primitive machine code for the PC part, the use of the serial communications and d
